Mother board temp in chassis is normally about 10 degrees hot. -- Yours is 36 deg C which is in the correct range and with that monster video card, very cool.

CPU at idle runs between 45 and 50 if the system has been running more than a few minutes.CPU under max loading -- 55 to 65 = Great 65 to 75 = OK Over 75 (or more correctly, Tcase max +10) and I would do something.

Assuming all the PCIe slots are the same, you could try moving the video cards away from the cpu since any heat it is radating from the card will be sucked into the CPU fan.

The big question is how are the therimals under load?

You can use CPUID hardware monitor to track your therimals under normal working conditions..

Ok Foti, I have a few comments and questions after checking your new and old memory at Corsairs's website.

Your new memory is a 12GB kit, while the old is a 6GB kit, or did you have two of the 6GB kits, that is not clear in your post.

The new memory is a Corsair Vengeance set, which has very tall heat sinks, a well known feature of that model. The old memory seems to be a more standard type of DDR3 memory, without tall heat sinks. Is that correct?

The memory voltage is not overly high at 1.5V, but if you changed from 6GB to 12GB, that will add some more stress on the CPU's Integrated Memory Controller (IMC), which could cause some increase in CPU temperature.

I noticed in your last picture, and from your post, that you are using the standard Intel CPU cooler. Is that because your CM V10 no longer fits because the memory heat sinks are so tall? That is a common problem when using DIMMs with tall heat sinks and high performance CPU coolers, the CM V10 being a perfect example of that situtation.

You cannot expect the standard Intel CPU cooler to perform in the same way as a CM V10, if they did, what is the point of all the after-market CPU coolers?

Ok, I'm glad you were able to fix things and improve your CPU temperature.

One comment, you listed your hardware and have this entry:

CPU i7-930 2.8GHz (stock no OC)

But in your pictures of the AIDA64 screens (which I can't copy and paste from) your CPU is at 4000MHz, with a Multiplier and BCLK of 20 x 200. Not a problem or anything, and getting those temperatures at that OC even with water cooling is excellent. You obviously did a copy and paste of your hardware information, since it has the stock Intel cooler in the list. You should let people know you reached a high OC with great temperatures, even at a Vcore of 1.356V. We can also see that individual Core temperatures are as high as 15F above CPU temperature, which some people have been asking about. I really wonder how much we can trust the Core temperatures. Your X58 and ICH10R temperatures are normal too.
